      MDEV-452 Add full support for auto-initialized/updated timestamp and datetime · bc4a4567
      unknown authored
      Generalized support for auto-updated and/or auto-initialized timestamp
      and datetime columns. This patch is a reimplementation of MySQL's
      "WL#5874: CURRENT_TIMESTAMP as DEFAULT for DATETIME columns". In order to
      ease future merges, this implementation reused few function and variable
      names from MySQL's patch, however the implementation is quite different.
      
      TODO:
      The only unresolved problem in this patch is the semantics of LOAD DATA for
      TIMESTAMP and DATETIME columns in the cases when there are missing or NULL
      columns. I couldn't fully comprehend the logic behind MySQL's behavior and
      its relationship with their own documentation, so I left the results to be
      more consistent with all other LOAD cases.
      
      The problematic test cases can be seen by running the test file function_defaults,
      and observing the test case differences. Those were left on purpose for discussion.
